CAN-WRAPPING- MACHINE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed February 5, 1916. Serial No. 76,437.

T 0 (Mi whom it may concern:

Be it known that we, FREDERICK H. KNAPP, a citizen of the United States, residing at Baltimore, State of Maryland, and HAYWOOD Gr. DEWEY, a citizen of the United States, residing at Vilestminster, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in Can-Wrapping Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to labeling machines, of a character adapted to apply and affix labels to cans, cartons, or the like.

One of the main objects of the. present invention is to provide novel and improved can stopping and escapement mechanism, quite useful wherever applicable, for instance at either the inlet or discharge .end of a labeling echanism, and said escapement mechanism being of a positive and highly eflicient character, as well as strong and durable in use.

Further the invention includes can stopping and 'escapement means of improved construction adapted more especially for the forward or can inlet end of the machine, said escapement means including a member or members movable into and out of the path of a foremost can, and having operatively associated therewith an auxiliary can stopping member, adapted to move into and out of the path of succeeding cans, the said members being so constructed and arranged that as the first mentioned member is moved out of the path of the foremost can to release the same, the second mentioned member is moved into the path of succeeding cans to interrupt the 'movement thereof.

It is also contemplated by the invention to provide novel and improved can stopping and escapement mechanism at the discharge end of the labeling machine proper, said escapement mechanism in the embodiment of the invention here-in illustrated having associated means for delivering the labeled cans one at a time from the labeling mechanism. In the present embodiment of the invention, the said can delivery means is adapted to directly transfer a labeled can to suitable mechanism for foldlng pro ecting edges of the label over the cues of the cans.

The invention in its preferred embodiment is illustrated and described herein as having more particular reference to a comb ned can labeling and Wrapping mechan sm, that is to say a machine having mechamsm to apply and affix about the periphery of a can a label, the edges of which project beyond opposite ends of the can, and mechanism to foldsaid projecting edges over and in snug contact with the ends of the can, and the invention in this particular includes means whereby the said labeling mechanism and folding mechanism may be readily detached from one another to' the end that either of said mechanisms may be independently operated, the one as a labeling machine and the other as a wrapping machine. A further feature of the invention resides 1n the provision of novel and improved pastlngmechanism adapted to apply paste, cement or the like to the. periphery of the cans at the edges thereof, which is of especial advantage and usefulness in that embodiment of the invention wherein a mechanism is employed to fold the projecting edges of the label over the ends of the can, it having been ascertained that when the label is secured to the can at its edges, the same may be more readily and neatly folded without the likelihood of breaking or damaging the label at this point. J 0 her and further improvements, and novel details in the construction and arrangement of the various parts of the invention will be appreciated from the description to follow which for a clear understanding thereof is to be considered in connection with the accompanying drawings forming a part thereof and wherein is disclosed for the purpose of illustration a convenient and satisfactory embodiment thereof.

In the drawings Figure 1 is a front elevation of the ma chine;

Figs. 2 and 3 are detail views enlargedof the can feed and escapement mechanism at the outlet end of the ma hine;

Figs. 4 and 5 are detail views enlarged refer to' corresponding parts throughout the I of the can feed and escapement mechanism at the inlet end of the machine;

Fig. 6 is an enlarged detail view showing more particularly the actuating means of the escapement mechanism at the discharge several views, 1 is a" supporting frame mounted upon suitable legs or standards 2 conveniently havingroller supports 3 at the base thereof. 4 is a can feed runway or chute at the forward end of the machine. As is usual in this type of machine, the feed chute or runway is preferably supported at a downward inclination toward the front end of the machine, and said runway may be pivoted to the framework in any desired manner, whereby when the machine is not in use, the runway may assume an upright position against the front end of the machine, as usual. Suitable main runway'bars 5 are supported in any desired -anism is suitable pick up pasting mechanism including a paste pot or receptacle 16 manner upon the framework of the machine, and suitable guides for the endsof the can comprise a stationary guide bar 6 andan oppositely disposed yieldable guide bar 7, the latter being preferably .of sheet metal, whereby the same may yield at any point throughout its length, and the said bar 7 be yieldably supported as by spiral sprin s.

be stationary guide bar 6 as well as t e yieldable guide bar inthe embodiment of theinvention herein illustrated preferably terminate at the forward edge of the label receptacle, the forward end of the guide bar curved extension 8 fora purpose-to be here- 6 having an upwardly and rearwardly separate application for patent filed concurrently herewith. The runway bars 5 at points overlying the label receptacle are cut-away whereby to permit the cans to con tact directly with the labels in the receptacle and pick up the uppermost'label, it being observed that the cans previously have had applied thereto paste for picking up the labels. Adjacent the rear end of thelabel receptacle is a lap end pasting mechanism 11 of any approved type.

The means for moving the cans along the runway preferably takes the formof one or more endless belts or conveyeis 12 mounted upon suitable roller supports 13 and 14, the

is a detail view of the can pasting indicated by the roller support 13 constituting a drive wheel for the various movable parts of the apparatus, said wheel being fixed upon a shaft l5 which latter is driven in any desired manner as by power mechanism or a suitable handle connected thereto.

In view of the fact that the labeling mechanism generally indicated by the numeral 00 and including the automatic feed for the label support, the lap end pasting mechanism and the driving mechanism for these parts is preferably substantially the same construction asthat illustrated and described in the patent to Knapp and Dewey, No. 1,271,724, application for which was filed February 5, 1915, it is deemed unnecessary to specifically describe the same herein. Likewise in the same patent is illustrated and described the endless belt-supporting mechanism and the driving connection therebetween and the other parts of the mechanism including the labeling mechanism, and it is not necessary to refe'r to the same in detail herein, no claims being predicated specifically on these features. r I Arranged forwardly of the labeling mechdetachably supported as by hangers 17 upon the runway bars 5, said pot being adapted to contain paste or cement adapted to be delivered directly on tothe can. 'Mounted in the paste pot is a suitable pasting device .comprising a rotatable shaft 18 mounted in suitable bearings, one end of'th'e shaft projecting beyondthe side of the paste pot and having suitable gear connection; 19 with the shaft of, the roller support 14: in any desired manner. The pasting device properincludes a series of annular center disks 20 and end disks 21, the latter being separated from the center disks by intervening spaces, and all of said disks being preferably connected to an integral hub 22. It is desirable in the present instance to apply paste to the cans ,at the extreme outer edges thereof and the end paste disks 21 are designed primarily for this purpose. By reason of this peculiar type of pasting mechanism, it will be observed that the label will be secured at the extreme outer edges of the can when the same are picked up byv the can in the rolling movement of the latter along the runway,

and this is of material importanceparticularly wherethe labels to be applied-are of The labels being tacked to the can at the extreme edges thereof cooperate with the folding mechanism to insure a neat and smooth fold and obviate the likelihood of breaking or wrinkling the label at this point in the folding operation. To accommodate for the pasting mechanism engaging the can porting the can in its movement along the runway. A suitable paste scraper member 24 is adj ustably mounted as by bolt and slot connection 25 upon the paste pot and regulates the amount of paste taken up by the various disks -21.

From the description thus far, it will be noted that as the cans are fed along the runway bars 5, through the medium of the endless carriers 12, the cans come in contact with the pasting disks 2021, spots or daubs of paste being taken up by the can at the center and outer edges thereof, and in the continued movement of the can, the pasted area thereof will contact with the forward edge of the uppermost label on the support, the support being periodically fed upwardly to accommodate for the diminishing supply thereof. As previously described, the label support is of a character to accommodate labels of a width greater than the length of the cans, and this makes necessary terminating the guide bars 6 and 7 at the forward end of the label support, the guide bar 6 however, having the curved extension 8 thereby accurately positioning the can with regard to the label, and because of the curved character of said extension 8 the projecting edges of the label which has been picked up by the can will, in the rolling movement of the can, pass under the curved surface of theextension, without being dis placed or injured. Obviously the opposite guide bar 7 may have a similar curved extension 8, if desired. The continued movement of the can over the label receptacle, which latter takes the place of the runway bars 5, at this point causes the label to wrap about the can, and the lapped end of the label having previously been supplied with paste through the medium of the lapped end pasting mechanism 11, said lapped end of the label will overlie the oppositely attached end of the label and be secured in place.

Arranged above the runway and at a point between the conveyer belts 12 is a suitable yieldable member preferably taking the form of a brush 25 adapted to yieldablyengage the periphery of the labeled can and thereby tend to smooth out any wrinkles in the label.

Arranged rearwardly of the brush member 25 and in a cut-out part of the runway bars 5 is a suitable yieldable pad 26 of a length extending from end to end of the can, which said pad is preferably arranged in substantially vertical alinement with the feed belt supporting rolls 13, with the result that as the labeled can moves over the yieldable pad'26, the rollers '13 will tend to iron the label and firmly aflix the pasted portions thereof to the can.

At the rear end of the runway bars 5, there is provided a suitable receiving pocketor stop for the cans, the same being preferably formed by relatively wide segmental plates 28 secured one to each of the terminals of the bars 5, the bars 5 at their points of connection with said plates 28 preferably inclining downwardly toward said plates and the plates forming a depression in the runway with the free portions thereof projecting a considerable distance above the plane of the runway thereby affording a substantial stop for the cans. The cans may be lifted from said stop by any desirable mechanism, or even by the hand of the operator. More particularly, is this true, assuming that the folding mechanism is not to be employed and that the labels which are applied to the cans are not of a character to project beyond the edges to be folded against the ends of the can in which event the labeling operation will be complete when the cans reach a position in the receiving pocket 28. In the preferred embodiment of the invention, however, it is contemplated to not only label, but wrap the cans, and with this in view, suitable transfer mechanism is provided for picking up alabeled can from the pocket 28 and delivering the same di rectly intothe folding mechanism 10, said pick up mechanism as illustrated, taking the form of a rotatable reel or carrier wheel 80 having a series of segmental pockets 31 in the periphery thereof, said Wheel being of a character to project into the space between the segmental plates 28, and the operation of said wheel being'so timed that when a can assumes a position in the pocket formed by said plate 28 a segmental part 31 of the wheel will engage about the periphery of the can when the same will be lifted out of said pocket and fed directly to the folding mechanism, as will be more clearly app1e ciated from the illustration and description of the folding mechanism per 56 which constitutes the subject-matter of the separate application filed concurrently herewith.

The wheel 30 and associated parts of the folding mechanism are mounted on a suitable framework 32 having suitable roller supports 33 at the base thereof and said framework being detachably connected in any desired manner when properly positioned as by bolts 32 to the framework 7 of the labeling mechanism proper. Likewise, the

wheel 30. and associated movable parts are tachable universal coupling mechanism 36 belt rolls 13.

character of the rock arm 41 and parts car-' with a drive shaft 37 adapted to actuate the various movable parts of the folding mechanism. r a

In order to separate succeeding cans and interrupt the movement thereof while a foremost can is in the pocket 28 to be picked up by the conveyer member 30 of the fold ing mechanism, there is provided suitable can stoppin or spacing mechanism preferably of the Following construction:

39 is a suitable roller member mounted for free rotation upon 'a shaft 38 which latter in turn is connected to a downwardly projecting bracket extension40 at the outer free end of a rock arm 41, the latter taking the form of a bell crank lever, the opposite end thereof being illustrated at 42. .The roller members 39 preferably comprise a plurality of separated rolls as illustrated more particularly in Fig. 2 and conveniently the bell crank lever 41 andassoci-v ated parts are duplicated, the two members being connected to one another as by a transverse bar 43. The bell crank levers 4142 are loosely mounted upon a shaft 44 which shaft may be anvintegral extension of the shaft 16 which supports the. feed Because of the elongated ried thereby, it will be observed that the roller or free end of said arm will move downwardlyby gravity, and this downward movement is limited by a suitable adjustable stop 45 in the form of a threaded bolt mounted in a rearward extension 46 of the rock arm, the said bolt being adapted to engage a suitable stop or abutment 47 secured to the framework of the machine in any desired manner. By adjusting the bolt the downward limit of 'movementcof the rollers 39 may be varied as'desired. The

means for actuating the rock arm :41 will now be described, it being noted in this connection, however, that minor changes indetails of construction may be resorted-to without departing from the spirit of the invention.

Mounted upon the shaft 16 is suitable pinion 48, the same adapted 'to-meshwith a suitable gear 49 mountediupon a stub-sh aft 50 rotatably mounted in any. desired manner on the framework of the machine. Fixed to said stub-shaft is a'suitable cam disk51, the same adapted at its periphery to be engaged by a roller bearing 52 project ing laterally from a coupling lever 53- pivoted at 54 uponan'elongated reciprocating arm or bar 55. The reciprocating arm 55 is slotted intermediate its ends at 55* and is mounted upon the'shaft 5O atthis point, the said arm being pi-votally connected at one end at 56 with the upper end of the extension 42 of the bell crank lever.

A suitable spiral spring 57 connected at one end 58 to the coupling lever 53 and at its opposite end to a pin 59 on the reciprocatmg arm 55 tend to normally hold the coupl ng lever in one of its positions of I movement, and a cut-out portion 60 adapted to engage the pin 59 serves to lock theparm 50 against rearward movement at a time when .the rollers at the free. end of the'bell its rotatable movement in contact with the roller 52, will move the locking end, 6010f the coupling lever 53 out of locking position, this end of the couplinglever. being 'elevatedfor this purpose, and the oppO- ite offset end 61-of the coupling lever being adapted to contact with'a stop or abut ment 62 at the free end of the reciprocat ing arm 55; The coupling lever 53 at this time constitutes in effect a'fixed part of V the reciprocating, arm 55. with the result that the continued movement of" the cam disk will impartrearward movement to the reciprocating arm. and; tilt the bell crank lever"41:42 about the pivotal support 16- 14, thereby elevating the roller end of the rocking arms.

The operation of the last described can stopping and releasing mechanism may be reviewed as follows: 7 V 7 Assuming thatthe shaft 50f is being rotated by its pinion and gear connection with the shaft 16, and that the rollers 39 are in elevated position or out-of the path of the cans, a foremost canwill fall into the can receiving pocket 28 of the runway. At. this time, it is desirable to.lower'the rollers 39 into contact with :the foremost can and betweenthe foremost can and the next succeeding can, thereby separating these cans and interrupting the continued movement of the succeeding cans while the foremost roll is being rotatedo'ut of-the pocket by the rotatable reel moving in the space between the oppositely disposed members 28 of the pocket. The cam disk 51 when the rollers 39 are in upward position, 'will act to maintain the coupling lever 53-with its end 61 incontact with the abutment 62; The continued' rotation'of the cam 51 will bring a reduced portion of saidcam into contact with the roller 52 of the coupling lever, thereby allowing the roller or weighted end of the rockarms 4142 to gradually lower, by gravity, into lowermost positionf and when the limit of'the lowering movement of the rollers is reached, a further reduced portion of the cam 51 .will permit the spring 57 to move the coupling lever 53 about the pivot 54 when the locking end 60'of said coupling lever will contact with the stop 59. Because of the construction of cam, the rollers 39 will be maintained in lowered locked position for sufiicient interval to permit of the foremost can being elevated out of the pocket and moved into position to be acted upon by the folding mechanism proper. After suiiicient interval has elapsed a raised portion of the cam 51 in contact with the roller 52 will tend to rock the coupling lever out of locking position with the stop 59, and after the opposite end 61 of the lever contacts with the stop 62 the reciprocating lever 55 will be moved rearwardly by the cam in,

the manner previously described, which results in upward releasing movement of the rolls 39.

Another feature of the invention resides in novel spacing mechanism at the-inlet end of the machine, said mechanism being adapted to cause the delivery of the cans one at a time, from the feed chute or runway to the main runway of the machine, to the end that the cans may be individually operated upon by the various pasting and labeling means heretofore referred to. This spacing mechanism is of a character somewhat similar to that heretofore described as arranged at the discharge end of the labeling machine, and it is unnecessary to describe in detail the construction and operation of these parts which may be readily understood and followed from the description above, the parts of the escapement mechanism at the forward end of the machine which correspond to the same parts at the rear end of the machine being given the same reference character numeral in the drawing with an alphabetical exponent. In that embodiment of the spacing mechanism at the forward end of the machine, the roller members 39 are adapted in the lowered position of the rock arms 41 -42 to contact the foremost can forwardly of the latter. Loosely connected for rocking movement upon the shaft 38 of the rollers 39 are arms 65 separated from one another a sufficient distance to overlie the ends of the cans, and said arms being connected at the free end thereof by a stop bar 66. Pivotally onnected to said arms 65, intermediate the ends thereof, are inclined upright supports 67 having a slotted portion 68 at the lower end thereof adapted to engage over suitable pin projections 69 on the framework of the machine. The normal position of the arms 65 and supporting members 67 when the rollers 39 are in position to stop the foremost can, is illustrated more particularly in Figs. 1 and 4:. Now as the roller members 39 are elevated out of the path of the foremost can in the manner heretofore described, the stop bars 66 being guided by the supporting members '67 will be lowered into a position between the foremost can and the next succeeding can and maintained in this position, whereby to interrupt the movement of succeeding cans,

until the forward can has moved along the main runway the proper distance, when the roller members 39 will be lowered and the stop bar 66 elevated, allowing succeeding cans to move down the chute until the same contact with the rollers 39.

The respective can stopping and escapement means at the opposite ends of the labeling machine proper are so timed that as the roller members 39 are in lowered position or in the path of the cans, to interrupt the movement thereof at the feed or inlet end of the machine, the roller members 39 at the opposite end of the machine will be elevated to permit the escape of a can, it being preferred and in the illustrated embodiment of the invention, the parts are arranged whereby to have but one can at a time in operative association with the labeling mechamsm.

The roller members 39 and 39 constitute anti-friction engaging surfaces readily riding over the cans as the latter are released thereby.

Should it be desired to utilize the labeling mechanismto the exclusion of the folding mechanism, it will only be necessary to release the detachablesecuring bolts 32 connecting the respective frames 1 and 32 and to release the drive coupling means 36, when the labeling machine and folding machine ma be independently operated as such.
